Dynaflow, Inc. is actively involved in developing and applying Computational Fluid Dynamics (CFD) codes. Our developments are centered on the state-of-the-art, computationally efficient Boundary Integral, asymptotic expansion methods, and Vortex Element Methods, as well as Reynolds Averaged Navier Stokes Equations solvers.

CFD codes are available or under development to solve varied problems including:

  • 2DynaFS©, 3DynaFS©: 2-D and 3-D free surface and bubble dynamics with structural interaction using boundary element methods
  • MultiBBL: The dynamics of "clouds" of bubbles in shear and quiescent flows using boundary element methods and asymptotic expansion methods
  • 2DFlow®©: Flow field and particle trajectories around arbitrary 2-D airfoil shapes for potential flows containing drops or solid particles using singularity methods
  • StressWave: 1-D nonlinear elastic and plastic stress wave propagation in multilayered media due to impacts using method of characteristics
  • DF_UNCLE: Dynaflow version of UNCLE. A 3D unsteady incompressible Navier-Strokes solver which is capable of dealing with moving free surface using moving Chimera overset grid scheme.
  • DynaSim: Four degrees of freedom ship maneuvering simulations including the interaction of multiple ships and complex harbor simulations with preplanned routes and automatic collision avoidance logic
  • DF_MULTI_SAP®: A Bubble Nuclei Dynamics and Trajectory Model for Cavitation Inception and Noise Studies
